ARMV7: OMAP4: Add struct for twl603x data
The data struct is used to support different
PMIC chip types. It contains the chip type and
the data (e.g. registers addresses, adc multiplier)
which is different for twl6030 and twl6032.
Replaced some hardcoded values with the
structure vars.
Based on Balaji T K <balajitk@ti.com> patches for TI u-boot.
